Abstract
Efficient computation is a key consideration in computational electromagnetics, especially for complex VLSI structures that contain thin dielectric layers or electrically small objects. Due to the CFL stability condition, it is very inefficient to apply the conventional FDTD method to thin-layer structures because fine mesh (and therefore small time step) is required. In this paper, the unconditionally stable ADI-FDTD method is employed to circumvent the difficulty. With applications in computing effective dielectric constant (/spl epsiv//sub eff/) and characteristic impedance (Z/sub 0/) of cylindrical microstrip lines, it is shown that the computation time with the ADI-FDTD method is much shorter than that of the conventional FDTD method without sacrificing modeling accuracy.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
